Embodiment

[0014] Example: such as figure 1 , figure 2 , image 3 As shown, a pipeline joint device includes a joint main body 10, a sleeve body 20, a PE fixing sleeve 30, a crimping sleeve 40, and a high elastic sealing ring 50. The joint main body 10 can be manufactured according to user requirements. Various sizes and shapes are available for users to choose.

[0015] The bottom of the sleeve body 20 is provided with an engaging groove 25, and a PE fixing sleeve 30 is fixed on the engaging groove 25. The inner hole of the PE fixing sleeve 30 is stepped, and the small hole 32 at the rear is closely fitted and fixed with the engaging groove 25. The large hole 33 at the front part is used for the insertion of the crimping sleeve 40, and a circle of barbs 31 protrudes from the front edge of the small hole 32. When the crimping sleeve 40 is inserted into the large hole 33, the barbs 31 hook the front end of the crimping sleeve 40 The inwardly bent chamfer 42 is used to fix the crimping...

Abstract

This invention discloses one kind of pipeline attachment installment, including the attachment main body, wraps the synthesis, compression-joins the drive pipe, wraps on the synthesis to be equipped with several ring groove, ring groove in is equipped with the high elastic seal packing collar, states a set of synthesis the base to be equipped with the card to gather the trough, stops gathers on the trough fixedly to have the PE fixed wrap, the PE fixed wrap inner loop is equipped with overhang a barb, compression-joins front end the drive pipe inlet the bevel edge to insert the barb the addendum circle and is lived by the barb hook; After this equipment and the tube body union has the stable embedment effect, not influence which contracts the material thermal expansion, may avoid when the construction compression-joins the drive pipe to be separated from the position, guarantees compression-joins the drive pipe, manages the body, wraped the synthesis effective compression connection to be fixed, enhanced the compression connection fastness and the tensile strength.

Description

technical field [0001] The invention relates to a pipeline joint device, especially for various large, medium and small joints of aluminum-plastic composite pipes, PEX and plastic pipes. Background technique [0002] In the prior art, the applicant once designed joints for aluminum-plastic composite pipes and plastic pipes, and applied for a Chinese invention patent, the patent number is ZL00116071.0, and the authorized announcement number is CN1128305C. It is used for the connection of aluminum-plastic composite pipes or plastic pipes. It includes: a pipe joint body with a fitting body, a crimping ring, and a high-elastic sealing ring; High elastic sealing ring on the edge of the ring groove; there is a circular viewing hole near the front end of the crimping sleeve to check whether the pipe body is installed in a safe positioning position. After the pipe joint is combined with the pipe body, the fit is stable. Due to the high elasticity Sealing ring, so its function is no...
